IMPROVEMENT IN WASH-BOILER ATTACHMENTS.

Specification forming part of Letters Patent No. 134,017, dated December17, 1872.

To all whom it may concern:

Be it known that we, WILLIAM TINNER and JOHN G. TREGEAR, of Stocktominthe county Luzerne and State of Pensylvania, have invented a new andImproved Wash-Boiler Attachment, of which the following is aspecification:

Figure 1 is a plan or top view of our improved wash-boiler attachment.Fig. 2 is a vertical horizontal section of the same taken on the planeof the line 0 c, Fig. 1. Fig. 3 is a. vertical transverse section of thesame taken on the plane of the line k 70, Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to awash-boiler attachment in which the clothesto be cleaned are exposed to streams of hot water that pass through thesame in one direction and take away all impurities and rapidly securethe desired effect.

The apparatus shown in drawing isa device to be placed within anordinary wash-boiler for creating the desired currents of water throughthe goods. This inserted device consists of an oval rim, a, of such sizeas to fit the ordinary wash-boiler when placed within the same, asindicated in Fig. 3. This rim holds two bottoms, b and d, the lowermostof which, d, is about an inch or more above the bottom of the ordinarywash-boiler that contains the device. Above the upper bottom b isarranged a sort of rack, e 0, upon which the clothes to be'cleansed areplaced. From the ends or sides, or either, of this device projectvertical tubes or hollow pillars f f, which have apertures g g at theirupper parts. The upper bottom I) is funnel-shaped, and open in themiddle, so that the water on top of it may flow down into the space 72.which is formed between the two bottoms b d.- This space h communicateswith two boxes, t i, that are arranged beneath the lowerbottom d.Openings in the sides of these boxes 2' i are or may be closed by meansof valves j j, which are clearly shown in Fig. 3. These valves, it willappear, are at the sides of the space I, which is formed between thebottom of the containing boiler and the bottom 61 of the insertedboiler.

After the instrument herein described has been inserted within theordinary boiler, the

clothes placed upon the rack e, and the suds introduced and heatapplied, the effect will be as follows The water in the space I,becoming overheated to create steam, will, by its pressure of expansion,first close the valves j j.

The steam will then ascend in the hollow pillars f f with the hot waterand cause a constant stream of such heated water to be brought throughthe tubes 9 9 upon the clothes on the rack. As quick as the pressurewithin the chamber Z is diminished, the valves j j will be opened by thepressure or weight of the water from within the boxes 3 i. In thismanner circulation will constantlybe going on but it will be seen thatthe water poured upon and through the clothes always passes in onedirection, thus taking away all impurities.

Very large as well as very small quantities of clothes can thus berapidly, effectually, and economically cleansed without becoming in theleast injured or being unnecessarily handled.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The wash-boiler attachment, composed of therim a, bottoms I) 61, valves jj, and hollow pillars f, all arran gedwith respect to each other, substantially in the manner herein shown anddescribed.
